Struct TaskResultMetadata 

pub struct TaskResultMetadata { /* private fields */ }

Available on native and crate feature tasks only.

Task result metadata with status information

Examples

use reinhardt_tasks::{TaskResultMetadata, TaskId, TaskStatus};

let metadata = TaskResultMetadata::new(
    TaskId::new(),
    TaskStatus::Success,
    Some("Task completed successfully".to_string()),
);

assert_eq!(metadata.status(), TaskStatus::Success);

Implementations

impl TaskResultMetadata

pub fn new( task_id: TaskId, status: TaskStatus, result: Option<String>, ) -> TaskResultMetadata

Create a new task result metadata

Examples

use reinhardt_tasks::{TaskResultMetadata, TaskId, TaskStatus};

let metadata = TaskResultMetadata::new(
    TaskId::new(),
    TaskStatus::Success,
    Some("Done".to_string()),
);

pub fn with_error(task_id: TaskId, error: String) -> TaskResultMetadata

Create a failed task result

Examples

use reinhardt_tasks::{TaskResultMetadata, TaskId, TaskStatus};

let metadata = TaskResultMetadata::with_error(
    TaskId::new(),
    "Database connection failed".to_string(),
);

assert_eq!(metadata.status(), TaskStatus::Failure);

pub fn set_error(&mut self, error: String)

Set the error message while preserving result and status fields.

pub fn task_id(&self) -> TaskId

Get the task ID

Examples

use reinhardt_tasks::{TaskResultMetadata, TaskId, TaskStatus};

let task_id = TaskId::new();
let metadata = TaskResultMetadata::new(task_id, TaskStatus::Success, None);
assert_eq!(metadata.task_id(), task_id);

pub fn status(&self) -> TaskStatus

Get the task status

Examples

use reinhardt_tasks::{TaskResultMetadata, TaskId, TaskStatus};

let metadata = TaskResultMetadata::new(
    TaskId::new(),
    TaskStatus::Success,
    None,
);
assert_eq!(metadata.status(), TaskStatus::Success);

pub fn result(&self) -> Option<&str>

Get the result if available

Examples

use reinhardt_tasks::{TaskResultMetadata, TaskId, TaskStatus};

let metadata = TaskResultMetadata::new(
    TaskId::new(),
    TaskStatus::Success,
    Some("Result".to_string()),
);
assert_eq!(metadata.result(), Some("Result"));

pub fn error(&self) -> Option<&str>

Get the error if available

Examples

use reinhardt_tasks::{TaskResultMetadata, TaskId};

let metadata = TaskResultMetadata::with_error(
    TaskId::new(),
    "Error occurred".to_string(),
);
assert_eq!(metadata.error(), Some("Error occurred"));

pub fn created_at(&self) -> i64

Get the creation timestamp

Examples

use reinhardt_tasks::{TaskResultMetadata, TaskId, TaskStatus};

let metadata = TaskResultMetadata::new(TaskId::new(), TaskStatus::Success, None);
let timestamp = metadata.created_at();
assert!(timestamp > 0);
